The contract ones probably have better facilities. On the other hand, pay-by-the-month types only have the bare minimum - but of course, that's all many people need. For instance, a lot of guys don't need a yoga class, racquetball, or a sauna. Anyway, though, the contract ones sometimes give out free trials. In fact, at the moment, I'm using a 2 week one. However, though, it's pretty much a sure thing that the price will be very high once the trial is over.
